Is anyone doing research on this family?Grace (Stambaugh) was married to Dr. Jacob Charles Madara.Her parents were Frederick Stambaugh and Francena (Kauffman).Grace was born in 1868 and died in 1904 in Bedford, PA.Grace and Jacob Charles had one son that I know of.His name was Frederick Garland Madara born in 1899 and christened in 1901.I'd like to know if Jacob and Grace had any other children and what happened that they both died in their 30's?Thanks for any help.
